This very rare phenomenon has received the scientific name heteroparental superfertilization.
In Brazil, a 19-year-old woman gave birth to twins from different fathers after having sex with two men on the same day. This was confirmed by one of the newly minted parents, who passed a special DNA test, writes the Daily Mail.
The doctor who delivered the baby, Tulio Jorge Franco, said it was a one-in-a-million situation.
The girl collects the DNA of the man she thinks is the father, but after two tests, the results are positive for only one of the twins. Then she remembered that she had sex with another man that same day, and when the second partner passed the test, he turned out to be the father of the second set of twins.
“It is possible when two eggs from the same mother are fertilized by different men. The babies share the mother’s genetic material, but grow in different placentas. The case is very rare, the situation is one in a million, I don’t thought I would. see it in my lifetime,” added Franco.
It is known that there are only about 20 such cases in the world.
Local media reported that the children are now 16 months old, but Dr. Franco about the case this week. And now, one of the fathers takes care of the two children, supporting their mother.
Having twins from different fathers is an extremely rare phenomenon known as heteropaternal superfertilization. It occurs when a mother releases two eggs, which are then fertilized by two sperm from different men. Women usually have to have sex with two different men the day before or after ovulation in order for both eggs to be fertilized.
Although heteropaternal superfertilization is rare in humans, it is common in other animals, including dogs, cats, cattle, and rodents. In species where females have multiple partners, some males even develop strategies to ensure that their sperm enters the egg.
It will be remembered that a resident of Saudi Arabia gave birth to five pairs of twins. It happened at the beginning of this year.
